Hello, is there a way to parse string in numbers? And is there any way to check whether a program is a string or not without breaking the program? I'm thinking about trying and catching it would be a good idea?

string to check if a string is parsable without trying to parse the string To start trying to interpret as a number ...) For checking halfway, I think you can use Regex to check that there are only digits and periods of the string. You must use an attempt ... Hold the block though. although,.

How to parse a string in double, try it:

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' .

I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
